Synthesis and Characterization of a Novel Dialdehyde and Cyclic Anhydride

The acid treatment of a ruthenabenzene yielded an unusual
dialdehyde. Interestingly, this dialdehyde has notable anti-oxidative properties and resists even nitric acid. This stability
is confirmed by chemical and electrochemical experiments.
In addition, a stable cyclic anhydride is synthesized from
the dialdehyde via an environmentally friendly electrochemical method.
